From Bulbapedia, the community-driven Pokémon encyclopedia.
Gluttony (Japanese: くいしんぼう Glutton) is an Ability introduced in Generation IV. Nineteen Pokémon can have this Ability.
Gluttony causes the Pokémon to eat a held berry at 50% health as opposed to the usual 25% health.
Gluttony has no effect on the use of an Oran Berry or a Sitrus Berry, both of which are normally eaten at 50% health.
